GUIDE FOR PLANES.

SFEGIFICATION forming part of Letters Patent No. 729,725, dated. June-2, 1903. Application Sled June V23, i902- Serial No. 112,775. (Nomodel.)

To a/l/ whom t 'nw/y concern:

Be it known that I, JAMES W. BRADY, a citizen of the United States,residing at South Bend, in the county ofSt. Joseph and State of Indiana,have invented certainnew and useful Improvements in Guides for Planes;and` I do hereby declare the following to be a full,

clear, and exact description ofthe invention, such as will enable othersskilled in the art to` it is often necessary to alternately change fromone bevel toanother, and I provide devices which may be previously setto give the required angular adjustment when theguidej is reversed fromone angle to" the other to accurately bevel eachedge of the board.

With these objects in view theinvention consists in the novelconstruction of parts and their arrangement and aggroupment in operativecombination.

I have fully illustrated the invention in the accompanying dra-wings, inwhich- A Figure l is a side elevation of the plane and guide. Fig., 2 isau end elevation showing the guide adjusted for beveling the edges of aboard downward from its finished face. Fig. 3 is an enlargedend view ofthe guide. Fig. 4 is a section on the line a: of Fig. 3.

Referring tothe drawings, l designates the plane-stock, from one side ofwhich projects the threaded shafts 2, secured in place near the bottomin any suitable manner, but preferably screwed and held by jam-nuts 3,as shown. The` guide 4 is suspended from these threaded shafts by meansof downward and inwardly curved arms 5, having integral sleeves 6, whichare mounted onthe rods and capable of being moved back and forth'thereonto provide a lateral rectilinear movement for the guide, which whenadjusted to the desired positionmaybe held by the jam-nuts 7, screwingon the shaft at each end of the sleeve. The guide-plate 4 is providedwith a plurality of transverse ears 9, having a pivotal connection attheir centers with the arms 5, said ears also having.A concentric slotsl0, in which are mounted adjustable pins l1, having-binding-nuts 12itted on their projecting ends, adapted to engage the arm 5 and limitthe rotary movement ,oit the ear when the guide-plate is angularly adjusted to plane a beveled edge on the board. The central apertures in theears are engaged by the threaded shank of a thumb-nut 13, which is letinto an aperture in the end of the arm 5, said thumb-nut having a iangedbase 14 to provide a broad binding-surface on the arm.

By mounting the guide adjustably on a shaft projecting from the side ofthe planestock a horizontal rectilinear movement is provided for theguide, so that when the angular adjustment is effected by means of thefthumb-nut 13 the guide-plate may be brought `in under the face of theplane to the desired distance to form a bevel on Awork in which the sideof the board opposite the guide is provided with a cleat or otherobstruction for the plane-face. Such an application of the invention "isillustrated Vin Fig. 2, wherein a portion of a panel of a carriage-bodyl5, having a cleat 16, is shown, the bevel extending from the innercorner of the cleat 16.

When a double bevel is to be formed on the edge of a board, the pins 1lmay be adjusted to the required distance on each side of the arm 5, sothat the angular adjustment for each bevel may be alternately changedwithout resetting the pins, as they form stops for the guide-plate bycontacting with the arm 5. One of these angular adjustments `is shown indotted lines in Fig. 3.

Having thus described my invention, what I 'claim is l. The combinationwith a plane-stock, of a rotary guide, a support for said guide,adjustable devices carried `by the guido and adapted to engage oppositesides of the support to limit the f rotary movements off-the guide. t

2. The combination ofan plane-stock having a laterally-extended shaft,a'sleeve adjustable on the shaft and provided with an arm, a guiderevolubly mounted on the arm,

combination with the plane stock having shafts projecting laterallytherefrom, of a plane-guide horizontally adjustable on said shafts andconsisting of arms and a guide-plate having ears pivoted to said arms,and means carried by the ears on each side of the arms to limit therotary movement of the guide-plate when angularly adj usted.

I n testimony whereof I affix my signature in presence of two witnesses.

JAMES W. BRADY.
